SHIP-PROTECTOR.

Specication of Letters Patent.

Patented Feb. 26, 1918.

Application led September 5, 1917. Serial No. 189,781.

To all whom it may concern:

Be it known that I, WALTER PIASECKY, a citizen of Russia, but having declared his intention to become a citizen of the United States, residing at Cambridge, 6 Burleigh St., in the county of Middlesex and State of Massachusetts, have invented 'certain new and useful Improvements in Ship-Protectors, of which the following is a specification.

This invention relates to certain new and useful improvements in ship protectors.

The primary object of the invention fis to provide a protector in the form of cushion buiers arranged in series completely around the hull of the ship adjacent the Water line thereof, whereby a torpedo traveling toward the ship equipped with this -protector will fail in its operation by being cushionedv at the time of contact with the protectors and causedto change its direction of travel. Should the torpedo upon striking the protectors be exploded, such explosion would not reachv the side wall of the ship in view of the peculiar construction of the protecting bu'ers, the arrangement ther of being practically impenetrable, and the dama e to the adjacent buffer caused by the torpe o would be comparatively slight and inexpensive to .re lace.

ith these eneral objects in view and others that'wil appear as the nature of the invention is better understood, the same consists in the novel combination, construction and arrangement of parts hereinafter more fully described and then claimed.

In the drawing forming a part of this application and in which like reference characters designate corresponding parts throughout the several views,

Fi lre 1 shows dia ammatically in dotted lines a ship provided with the present form of protecting device in operative position thereon illustrating the device as completelyzsurrounding the hull of a ship.

Fig. 2 is a vertical sectional view t rough one of the protecting buffers and a portion of the ships hull.

Fig. 3 is an end elevational view of tb" device shown in Fig. 1, and e Fig. 4 is an elevational view of the inner wall of the buffer removed from the ships side.

Briefly described, the present invention aims to provide a protecting device for ships against the ravages of torpedoes and similar devices and the protective devices are 1n the form of buffers arranged in juxtaposition completely surrounding the ships hull above and below the water line thereof. Each bu'er consists of a plurality of metal plates such as steel alternately arranged with leather and lead sheets with the outer portion thereof comprising, preferably in the order named, relatively thick layers of cork, hemp and cotton, while a flexible covering, such as rubber incloses the same, there being provided retaining angle plates for securing the bulfers in' proper position. v

Referring more in detail to the-accom-l plate 11 being rubber, and in this orderA including a steel plate 12, a leather plate 13 While the next late 14 is of lead with an outer plate 15 o? leather. A relatively thick layer of cork 16 is superposed on the outer leather layer 15 while in the order named are superposed layers of hemp 17 and compressed cotton 18. As shown in Fig. 2 a flexible covering 19 as rubber completely in closes the buffer 6 and lies in contact with the outer layer 18 of cotton While the inner ends 20 thereof are clamped between the adjacent portions of the ships side 9 and the angle bars 7, it being noted that the portion of the coverin 19 adjacent the bars 7 is in substantially rictional contact therewith.

In-order further to cushion Athe buffer 6 there are provided resilient members arranged between the inner steel plate 10 and the outer face of the ships side 9, these devices being more clearlyshown in Figs. 2 and 4 and comprising rows of rubber buffers 21 having threaded plugsV received in the late 10 while the metal and leather plates liave registering openings 22 therein for the reception of bolts 23 having their heads 24 positioned exteriorly of the late 10 while the inner threaded ends thereo are provided with retainin means whereby the several metal and leat er plates, and cork and hemp layers are retained inl proper relative posilio tions. Compression springs 25 are arranged between the heads 24: of the bolts and the adjacent portions ot' the ships side, any suitable means being employed-'for retaining the springs in proper position.

From this detail description ot' the invention it is thought thatthe construction and operation thereotl will be readily apparent, it being noted that a torpedo striking the buffer willcomprcss the buffer and wlll be cushioned in the stoppage thereofwith the possibility that the torpedo lwill fail to explode, and even should the torpedo explode the same will occur at a point' so spaced from the ship as to cause no damage thereto.

While 1 have shown and described the preferable embodiment of the invention, it

Will be understood that minor changes may be made without departing from the spiritandscpe of the invention as claimed.

What'I claim as new is 1. A ship rotector embodying a plurality of juxtaposrtioned buffers, each including .in the order named steel, leather, steel,

. engagement with the outer face of the ships side, bolts extending through the plates and layers', -and a cushioned spring arranged between the inner face of the bolts and th outer face ofthe ship.

2. A ship protector embodying a lurality of juxtapositioned buers, each-inc uding a series of alternately positioned' metal and leather plates, cork, hemp and cotton layers superposed on said plates,a flexibleT covering Vfor the buffer and means engaging said' cox ering adapted for securing the same to the side of the ship. 3. A ship protector embodying a plurality of juxtapositioned' buffers, each including a series of alternately positioned metal and leather plates, cork, hemp, and cotton layers superposed on said plates, a flexible covering for the buffer and means engaging said covering adapted for securing the same to the side ofthe ship, and rubber blocks arranged between the outer side of the ships hull and the inner face ofthe buier.

4. A ship protector embodying a plurality of juxtapositioned buffers, each including a series of alternately 4.positioned metal and leather plates, cork, hemp and cottonlayers superposed on said plates, a flexible covering for the buffer, and means engaging said covering adaptedfor securing the same to the side of the ship, and compression springs arranged between the outer side ot' they shipsA hull and the inner face of the buler.

5. A ship protector embodying a plurality of juxtapostioned buffers, each including a series of alternately l positioned metal and leather plates, cork, hemp and cotton layers superposed on said plates, a flexible coverv ing for the buffer and means engagmg said covering adapted for securin vthe same to the side of the-ship, and rub er blocks arranged between the outerside of the lships. hull and the inner face of the buffer, and springs arranged between the outer side of the ships hull and the inner face of the buifer.l v l f 6. A ship-protector including a plurality of buffers intimately' assembled yin position upon, and encompassing the ships hull adjacent the water-line, each buffer comprising a plurality of alternating metal and leather plates, layers of cork, hemp and cot ton superposed with respect to said plates, a v flexible coveringfor the buffer, means for the attachment of said covering to the ships hull, resilient members interposed between and spacing the metal plate and the ships hull, and bolts securing` said plates of metal and leather and layers of cotton, hemp and cork together, and vpositioned in alinement with certain of said resilient members. 5

In testimony whereof I aix my si ature.
